To all whom it may concern:

Be it known that LKANUTEA. -ENLIN1), a'citizen of-the United States, and a resident 'ofSouth Nyack, in the county of Rockland and State of New York, have made'c'ertain new and useful"Improvements 1nA1r- 7 ships, of which the following is aspecificastability.

airships and more particularly to that type of airships embodying rigid gas conta ners, my object being the'provision of a construction applicable alike to large and small alrships and of a nature which will aiforcl maximum protection and safety with speed and effectiveness especiallyas regards lateral 'In carrying outmy invention, propose an arrangement wherein rigid cylmders are mounted in spaced; parallel relation upon relatively opposite sides of a car, the latter of which may be of variousstructures and supported by the connections maintaining the cylinders inthemelation stated, each of these cylinders embodying a series of connected though separate gas containers, whose number and size may be varied to a great extent, rigidly connected to one another in the series and sodisposed in relation to the supports between the'two cylinders as to avoid the necessity of encircling envelops and the like. These cylindrical gas containers may be substantially braced to prevent collapse and each cylinder, made up ofsection through one ofthe cylindrical containers.

Specification of Letters Patent, Aug.

present invention relates generally to "Fig. is vertical section through the connecting shaft at t pOll'lll between the con: tainers.

Fig.7 is "a detail perspective view of oer,

tain of the connections as-hereinafter de scribed." l i Referring now to these figures, my inventionproposes a pair of'longitudinal parallel cylinders which are disposed andconnected 1n substantially the same horizontal plane and which are connected and braced in this relation by means of aseries of horizontally dlsposed crossbeams 10, as well as a plurality of inclined beams 11, the latter'of whichare connected at their opposing inner ends to the opposite sides of a central longitudinal ridge bean'r712. This ridge beam 12, together, with: the inclined connecting beams 11, form a truss in respect to the transverse. connecting bars or beams 10, the

strut of. which tru'ss is constituted byfjthe supports: 13 of the navigating tower I14. TlllS'" navigating tower is gmounted on. the

nectedto ridge beanr 12 and'to certain lower horlzontal cross beams 10, the latter of which support the car 15 in suspended relation therebeneath and between the lower portions of the spaced cylinders. (The foregoing relation of the parts is made possible without the necessity for supports of an enveloping nature, by virtue of the particularconstruction ofithe two cylin- I ders, each of which is made up of a longitudinal series of cylindrical gas containers 16 whoseends are closed" and connected in spaced apart relation by'a hollow shaft 17 which passes axially through the several containers and is secured at its opposite ends to the conical end containers 18, the shape of which thus avoids excessive resistance to air. The several containers of'each cylinder have independent intake and outlet openings normally closedby plugs-19 and the like as seen in Fig. 3, and are spaced apart at their ends in the direction of the length of the two cylinders, thus providing for the connection of the outer ends of the transverse connecting bars 10 and the-inclined brace beams 11 to the hollow shaft 17 as seen in Fi s. 6 and 7. ach cylinder'is made up of several containers as previously described thus affordnpports 13', the" latter of.-which are confurthermore provided with a longitudinally extending and horizontally projecting wing or fin 20, rigid in connection therewith and outstanding therefrom, as particularly seen by comparison of Figs. 1, 3 and 41, so as to cooperate with the remaining structure and relation. of the parts of the airship as previously described informing an arrange ment having great lateral stability and without materially reducing its ability as to speed and ready handling for which purpose the car 15 may have the forward and rear propellers 21 and 22 as well as a vertical rudder 23, the car itself containing any suitable motor for the operation of the former and controls for the latter.

By thus constructing each of the cylinders with a plurality of independent containers, it is obvious that accidental collapse, perforation, or other injury to one of the containers, need not necessarilyresult in disaster as in the case of the ordinary airship and in fact,- it is contemplated that" con tainers will be used in sufficient number in each cylinder to permit of the desired operation even should. one or two of the containers be disabled for-any reason. i

It is obvious from the foregoing that my invention provides a. remarkably stable arrangement and construction as, applied to s t n? said ridgebeam, as descr1bed.$ H airships, as well as one of equal effectlveinders including transverse horizontal con-V necting bars formingv a car supporting frame and inclined brace bejams,othe outer ends of which are connected I110 said shaft 'between the containers, a longitudinal ridge beam to which the inner ends of theinclined brace beams are connectechand means connecting the ridge beam with the car supporting frame and forming with the ridge beam and bracebeams a trussforthe said frame.

2. An airship comprisingapair of longi ti idinal, spaced cylinders, ,each having a longitudinal series of independent containers in endwise spaced relation, an axial shaft extending through each of the cylinders and joining the several containersthereof, connections between the cylinders including transverse bars secured to the shafts of the cylinder," inclined brace beams, the: outerends of which are secured to said shafts, a

ridge beam to which the inner ends of the brace beams are connected, a car suspended from the said transverse bars, and a. navitower connected to said car and .to
